Gasoline usage in the United State = 390,000,000 per day = 9.2 million barrels.
142,350,000,000 gallons per year
How much Ethanol is produced each year?

Bushel of Corn:

• 1.5 lbs. Corn Oil
• 17.5 lbs. Protein
• 2.6 lbs Corn Meal
• 31.5 lbs Starch = 2.8 gallons of Ethanol

Carbohydrates = Ethanol

• 3 simple sugars (mono saccharides) = Glucose (dextrose), Fructose, and Galactose
• Combinations of these simple sugars make up ALL carbohydrates - Ex. Di saccharides or poly saccharides

Processes involved with conversion of complex carbohydrates to Ethanol

• Liquefaction
• Saccharifaction
• Fermentation
• Distillation
• Dehydration

Coskata Process for Cellulosic Ethanol

Coskata bought bySynata Bio


Coskata had been focused, via gas fermentation, on converting natural gas to fuels. We suspect that, given low oil prices, Synata Bio may steer that technology towards attractive opportunities in chemicals. Possibly acetic acid, propanol or n-butanol.

Dehydration - Molecular Sieves

• Water is an incredible small molecule when compared other molecules. It's approximate diameter is 2.75 angstroms. There is 100 picometers to 1 angstrom so this is 275 picometers or 0.275 nanometers. In an attempt to help illustrate this think about the centimeter. We all know a good estimation off the tops of our heads what a centimeter is. Now break that single centimeter into 10 million parts. Each one of those individual parts is one nanometer. A water molecule is about a quarter of that.
